Aikido spirituality for me seems to be about my ability (or lack of ability) to face my real demons. For me to learn to force myself when I am tired or lazy is a spiritual event.
To run into my laziness enough that I gotta deal with it appropriately is a spiritual event.
Aikido shows me myself, if I am willing to look, and honest enough to admit what I see. Aikido allows me the vehicle to force myself to be and do better. That's about as much as anyone can ask from a spiritual practice.
